APPLICATION OF STATIC BOLT-PRESSING PILE AND DRAWING OUT SOIL IN DRILLING HOLE FOR DEVIATION RECTIFICATION OF INCLINED BUILDINGS IN SOFT GROUND

The design and construction process of rectifying deviation of a six-story masonry building in Shanghai are presented.For traditional inclination rectification method of static bolt-pressing piles and drilling and drawing out soil,the piles are first jacked by anchor rods in the side of a building with larger settlement,then soil is drilled and drawn out in other side of the building.When the inclination building is rectified,some piles are jacked in the other side to prevent building from inclining.In this project,the piles were jacked while soil was drilled and drawn out.This shortened the construction time,and reduced the additional stress at pile top.And the additional settlement of building was allowed.
